Total solar eclipse in China in 2009?

On July 22, 2009, there will be a total solar eclipse of the century! The total solar eclipse lasted for 6 minutes and 38 seconds. The total solar eclipse belt will pass through China from India to the Pacific Ocean, and will pass through the densely populated Yangtze River basin. A total solar eclipse lasting 4-5 minutes can also be observed in China. Its total solar eclipse lasts for a long time, which makes astronomy enthusiasts regard it as a total solar eclipse that cannot be ignored.

Observation?

Warning: Don't look at the sun directly with naked eyes, and don't look at the sun through viewfinder, binoculars or astronomical telescope without proper filter in front of the mirror, otherwise it may lead to blindness!

In addition to visible light, the sun also emits quite strong infrared rays and ultraviolet rays, which will damage the eyesight in excess. Unfortunately, because cone cells and rod cells in our retina can't feel infrared and ultraviolet rays. Some can only effectively filter visible light, which will give you a feeling of "darkness" and may not be safe.

1.？ Sun filter glasses? /? Solar filter

A qualified filter paper should be able to filter at least 99.9997% of light.

To ensure safety, please check whether the glasses/filters are damaged before each observation. It is recommended to check whether the filter paper is suitable for looking directly at the sun or safe before buying. For what? Direct? Solar energy? Watch "and other words. If in doubt, do not use.

projection method

Use a telescope (preferably a refractive telescope) to project the image of the sun on a white paper, and then watch the image on the white paper. This method is safe and can be watched by many people at the same time, but the contrast of the sun image is low.

Pre-mirror filtering method

Install a specially designed solar filter in front of the telescope to reduce the brightness of the sun. The filter must filter out 99.9997% sunlight.

Note: Some solar filters installed at the eyepiece end may burst suddenly due to overheating of the focused sunlight, and are not recommended.

There is also a filter paper that is only suitable for photography. Don't install it on a telescope for direct observation.

First loss (first time? Contact)

The first eclipse marks the beginning of the solar eclipse. There is a gap in the sun from the west, which gradually increases and turns into a crescent shape. You can also see a crescent-shaped pinhole sun under the tree.

Video (video? Band)

A few minutes before eating food, I had a chance to watch a series of bright and dark videos, just like watching ripples in water. If it is covered with white cloth, it will be more obvious.

Bailey's? Beads)

About ten seconds before the eclipse, the moon nearly covered the whole sun, and only one ray of sunlight could pass through the valley on one side of the moon. This is the so-called "thunderbolt bead" phenomenon.

Diamond ring (diamond? Ring)

When there is only one bead left, a diamond ring is formed.

Chromosphere ()

The sunlight we usually see mainly comes from the photosphere. These bright lights mask the darker upper chromosphere.

A few seconds after the eclipse, when the moon blocked the photosphere below, the purple chromosphere was just a flash in the pan.

Corona (corona)

The corona is the outermost atmosphere of the sun, which can extend to several solar hemispheres. In particular, the shape of the corona changes with each total solar eclipse, which may be related to the solar activity cycle.

Finally, I wish you can watch the total solar eclipse. I am miserable, because I can't see Hong Kong this time. ........
